To make a long story short, some installers put stone veneer (centurion brand) in the wrong place on my new home. So now they want to remove it and re-use it on the other side of my home.

My question is... will removing and re-using the stones compromise the integrity of the stones? When they remove the stone, will the concrete wall they are removing it from be ugly, or will the mortar come off completely? If it does not come off completely, how would I remove it? If I leave any mortar residue, will that affect being able to re-apply stone veneer in the future?
